Security Bulletin
This security bulletin contains information about 2 vulnerabilities.
1) Memory leak
EUVDB-ID: #VU74299
Risk: Low
CVSSv4.0: 1.7 [CVSS:4.0/AV:N/AC:L/AT:P/PR:N/UI:N/VC:L/VI:N/VA:N/SC:N/SI:N/SA:N/E:U/U:Clear]
CVE-ID: CVE-2023-0836
CWE-ID:
CWE-401 - Missing release of memory after effective lifetime
Exploit availability: No
DescriptionThe vulnerability allows a remote attacker to gain access to sensitive information.
The vulnerability exists due memory leak as there are 5 bytes left uninitialized in the connection buffer when encoding the FCGI_BEGIN_REQUEST record. A remote attacker can force the application to leak memory and disclose potentially sensitive data to configured FastCGI backends.
MitigationInstall updates from vendor's repository.
